Hi Revansiddha Gaur,

I have tried to export ACA template named 'ACA Prime Test' on LB environment getting server error for below scenarios:

1. mapped employer EIN field

Getting error having following work log

Exception : Object reference not set to an instance of an object.
App Error Log : -

Action Name : ManualImportExport
Model : System.Web.Mvc.HandleErrorInfo

Company List

2. Unmapped field employerEIN and mapped it with employee class1.

Getting server error having following work log

ErrorMessage: Object reference not set to an instance of an object.
